Scherrer formula is often applied to X-ray-diffraction profiles for the size determination of small
size clusters. However, for small clusters this often leads to conflicting results in comparison to
other methods. A series of Pd-clusters of different size is studied by X-ray diffraction analysis
and transmission electron microscopy. The influence of size and structure on the results is
presented and discussed in comparison with theoretical calculations. It will be shown that the
different structure of small size systems are one main origin of the conflicts. The structure
problem can be overcome by using Fourier Transform of the X-ray diffraction pattern. The
importance of the knowledge of the cluster structure was demonstrated by showing its strong
influence on the hydrogen solubility.
